Tripp Lite 3 phase Switched PDU / Power Distribution Unit enables a variety of advanced network control and monitoring functions by giving IT managers the ability to turn on, turn off, recycle or lock-out power to each individual receptacle, monitor site electrical conditions and remotely monitor output power consumption per-phase or even per-receptacle. PowerAlert interface supports custom notification and control of user-specified remote conditions via email, secure web, SNMP, Telnet or SSH interface. Individually switched outlets can be controlled in real-time to remotely reboot unresponsive network hardware, or be custom programmed per user-defined power-up and power-down sequences to ensure proper operation of interdependent IT systems and prevent inrush-related overloads as network equipment is first energized. Unused PDU outlets can be electronically locked off to prevent powering of unauthorized hardware. PDU output current consumption in amps per-phase or per-receptacle can be displayed locally via visual meter and can be monitored via the web/network interface, with user-defined alarms to warn of potential overloads before critical IT mains or branch breakers trip. Supports in-rack environmental and security monitoring for advanced configurations with optional ENVIROSENSE temperature / humidity probe and rack access notification for up to 4 door sensors (SRSWITCH) or other user-supplied contact-closure sensors. Lighted display with scroll-button offers power consumption in amps for each phase or receptacle, IP-address self-identification and 180 degree display rotation for overhead or raised floor power feeds. Supports real-time monitoring of all reported functions with support for user-specified alarm and notification thresholds. Fully compatible with PowerAlert Network Management System / NMS Software, available via FREE download from www.tripplite.com
